Im on the lookout for a 5 string (bass obv), i feel ive spent enough
time on my jazz bass and feel like branching out a little on a 5
string, my budget goes up to about £600 absolute max, and was
just trying to get some opinions on the makes above plus any
other decent 5 strings you may know of within the price range. I
play mostly funk and metal/progressive. Also here's what ive been
loving recently. Thanks.

I'd go with Ibanez, but you should shop around everywhere, every brand, read every review, watch videos on YouTube of them, and even try to get decent used ones on eBay (that's how I got my tube amp for over a hundred dollars cheaper).

I would love to but theres a lack of chain music stores in the uk, i think the best i can do is to try a right handed spector and others, get the feel for them and make a general judgement based on that, its the best i can do really.
